ICE MARKER AND PLOW.

SPECIFICATTON forming part of Letters Patent No. 258,637, dated May 30,1882.

Application filed February 6, 1882.

To all whom it may concern:

Be it known that I, JOSEPH B. FISCHER, of Hamilton, Butler county, Ohio,have invented certain new and useful Improvements in Ice Markers andPlows, of which the following is a specification.

My invention relates to that class of icemarkers which are used to markout a field of ice previous to running over it with the ice- 1O plow,and has special reference to the guide by which the marker is made tofollow a previously-marked line.

Referring to the drawings forming part of this specification, Figure 1is a side elevation of a marker constructed after the principles of myinvention. Fig. 2 is a top "iew of the same. Fig. 3 is an enlarged viewof the forward end of the beam. Fig. 4 is an enlarged view of the rearend of the beam and a portion of the handles. Fig. 5 is a view of therear end of the marker, looking toward the front. A

The beam A'is formed in the usual manner, having the various teeth aattached thereto.

The lower ends of the handles A are attached to the beam A by theangle-plates a, and are braced in a manner to be hereinafter described.

The guides heretofore employed on ice-markers have been in form of aplate extending e nearly the entire length of the beam, and attached ateach end to the beam by a rod, which is hinged to the beam to permit theguide to be turned from one side of the marker to the other. This formof guide is objectionable for 3 5 the reason that it is unnecessarilyheavy, and is apt to bind in the groove in the ice in which it travels,and thus it soon gets loose and out of order. To remedy this defect Iemploy the short guide-plate B, located at the forward 0 end of thebeam. This short guide-plate is attached to the arm B, which in turn isattached to the rod or shaft O, journaled on top of the beam. It issometimes desirable to cut the blocks of ice larger than at other times,

and heretofore in order to do this it has been necessary to use aseparate marker for each different size of block; but I construct mymarker so that I am enabled to mark difl'erent widths of blocks bymaking the arm B in two (N0 model.)

sections, 1 and 2, the section 1, to which the guide-plate Bis attached,being capable ofsliding on the section 2 and of being secured in thedesired position bya bolt, 3, or its equivalent,

by which means the guide-plate may be set at different distances fromthe beam. A red, I), 5 extends frpm near the end of the arm B to theshaft 0, to properly brace the guide arm and plate. At the forward endof the beam is the end or clevis block D, which is bolted to the beam,and to which the clevis D is con- '60 nected. This end block is providedwith a bearing, d, in which the forward end of the shaft 0 is journaled.The rear end of the shaft 0 is journaled in the cross-bar c, whichunites the ends of the semicircular plate E, and this plate and thecrossbar c are secured to the beam A by the flanges c, which are boltedto the beam.

Bolted to the plate E are angle-irons or braces E, to which the handlesA are also bolted, bracing them securelyin position, thereby dispensingwith the rods which' ordinarily extend from the handles to the beam.

At or near the center of the shaft 0, I place a journal-box, d, theshaft at this point being round to turn freely in the journal-box.

To the rear end of the shaft 0 is attached the crank F, by which theshaft 0 may be turned. The purpose of this turning of the shaft is toreverse the guide-plate B from one side of the So beam to the other, asis necessary to mark back and forth across the field.

To hold the guide-plate down firmly on the ice, the crank F is providedwith a springpawl, Or, one end of which is capable of entering notches hin the semicircular plate E. When the guide-plate is on the ice on oneside of the beam the end of the pawl G is in the notch h onthe sameside, and when it is desired to reverse the guide-plate to the otherside of the beam the end 9 of the pawl is pressed down on the crankhandle, thus removing the opposite end of the pawl from the notch, andthe crank is turned over to the other side, and the plate is thusreversed. If it is desired to hold the guide-plate entirely from theice, the end of the pawl is allowed to enter the notch in the top of thesemicircular plate, when the guideplate will be held above the beam.

Vhile the spring-pawl G and the notches 7b are the devices which Iprefer to employ for retaining the guide-plate in the desired position,I do not confine myself to this special form of device, as other devicesmay be employed to accomplish the same purpose.

From the above description it will be seen that my improved marker islight and convenient and yet firm.

The ice marker and plow are sometimes combined in 0ne,in which case theguide-plate and its connections, as above described, are equallyadvantageous.

What I claim as new and of my invention, and desire to secure by LettersPatent, is

1. The beam A, having a shaft, 0, journaled to its upper edge, andextendingfrom the front to the rear end of said beam, in combinationwith the guide-plate B, attached to the shaft 0 by the adjustable arm B,the rear end of said shaft being provided with means for turning theguide-plate from one side of the beam to the other, substantially as andfor the purposes specified. v

2. The combination of the shaft 0 and the guide-plate B, connected. tosaid shaft by the arm B, said arm being constructed in two sections, 1and 2, one section being capable of sliding on and being secured at thedesired point to the other section, substantially as and for thepurposes specified.

3. The combination of the beam A and the shaft 0, extending fromthefront to the rear end of said beam, the front end of said shaft beingprovided with a guide-plate, 5, and the rear end with mechanism forrotating said shaft to carry the guide-plate from one side of the beamto the other, substantially as described.

4. The beam A, provided at its front end with the clevis-block D and atthe rear end with the bearing-plate c, in combination with the shaft (3,provided with the guide-plate B, one end of said shaft being journaledin the clevis-block and the other end in the bearing plate a, said shaftbeing provided with means for causing it to rotate, substantially as andfor the purposes specified.

5. The combination of the beam A and the shaft O, the latter providedwith a guide-plate, B, and mechanism for rotating said shaft to carrythe guide'plate from one side ofthe beam to the other, and for holdingthe shaft and guideplatc in the desired positions, substantially as andfor the purposes specified.

6. The beam A, provided with plate 0 and semicircular plate E, incombination with the shaft O, provided with the crank F, said crank andsemicircular plate being provided with means for causing the crank to beheld in the desired position, substantially as and for the purposesspecified.

7. The beam A, provided with the clcvisblock D and the semicircularplate E, said plate being provided with notches h, in combination withthe shaft 0, provided with the crank F and spring-pawl G, substantiallyas and for the purposes specified.

8. The beam A, constructed substantially as described, in combinationwith the shaft (J, journaled at each end of the beam and at or near thecenter in the clip or box (1, substantially as and for the purposesspecified.

9. The beam A, provided with the semicircular plate E, in coi'nbinationwith the handles A, secured to the beam by the plates to and to thesemicircular plate by the angle-irons or braces E, substantially as andfor the purposes specified.
